1831 GMT:Egypt. Visiting Cairo, US Secretary of State John Kerry said the Egyptian Government's need to agree a $4.8 billion loan from the International Monetary Fund is "paramount".

Kerry said he was certain that US cooperation with Egypt can only happen if Cairo "makes the right fundamental choices" regarding the talks with the IMF.

The Morsi Government said on Thursday that it will invite an IMF team to reopen talks.

"It is paramount, essential, urgent that the Egyptian economy get stronger, that it gets back on its feet," Kerry told Egyptian and American executives. "It's clear to us that the IMF arrangement needs to be reached, that we need to give the market that confidence."

The Morsi Government agreed the loan in principle last November but it was put on hold at Cairo's request amid political unrest and an inability of the President to implement tax rises necessary for the IMF assistance.
